1 Claim.

My invention relates to building material and more particularly to thetype of material that may be employed for constructing floors and Walls.

The object of my invention is to provide material that is composed of aplastic composition reenforced with an arrangement of meshed metal.

Another object of my invention is to construct the reenforcing mesh in amanner that will produce vertical metal walls interlocked with oneanother so as to provide maximum strength when used for floors or thelike.

Still another object of my invention is to provide vertical sections ofmetal forming a plurality of rectangular enclosures with apertures topermit the plastic material to be forced from one enclosure to the otherthereby assuring an even distribution of material.

A still further object of my invention is to provide a vertical sectionof metal with staggered auxiliary members disposed at right angle to thevertical sections thereby preventing the plastic material from beingforced through the rectangular enclosure when pressure is applied to thesurface.

It is manifest to anyone familiar with the art that fibrous materialsmixed with a liquid binder may be used to produce a desirablelight-weight building material that has excellent insulating andacoustical properties, but this material, due to the very nature of itsconstruction, has but very little strength unless sufficientlysupported, by inserting a reenforcement consisting of several metalstrips interlocked with one another and placed so that the sheet metalis in a vertical position and perforated to provide access from oneenclosure to the other, the plastic material will thus have a tendencyto distribute evenly over the entire area and be of equal consistency inall of the enclosures formed by the metal, when pressure is applied tothe plastic material. In this manner the plastic material, when allowedto harden due to a drying process, will support the sheet metal stripson all sides thereby allowing maximum strength with minimum weight andproducing a material that may be placed over joists or be supported byangle irons, thereby lending itself ideally as a support for a wood orcomposition ioor. The invention is fully disclosed in the followingspecification of which the accompanying drawing is a part and in whichthe separate parts of my improvements are designated by suitablereference characters in each of the views, and in which Fig. 1 is a planview of the metal reenforcing structure, forming separate enclosures andprovided with a plurality of staggeredly arranged members bent at rightangle to the metal walls to prevent the plastic material from forcingits way through When pressure is applied.

Fig. 2 is a side View of Fig. 1 illustrating the manner in which theapertures may be arranged" and also the manner in which the verticalwalls are slotted to telescopically support one another.

Fig. 3 is a perspective view of a section of the assembled reeniorcingstructure prior to the plastic material being applied, and

Fig. 4 is a perspective view showing the reenforcing structure embeddedinto plastic material having matched floor boards adherently applied 15to its top.

Referring to the drawing in detail wherein like characters of referencedenote corresponding parts, the reference It illustrates a plasticcomposition composed of fibrous material adherently joined by means of aliquid binder having adherent qualities. There is a reenforcing unitconsisting of sheet metal strips II and I2 slo-tted at I3 andtelescopically engaging and supporting one another thereby formingrectangular enclosures i4. The members II and I2 are held in a verticalposition by slots I3 and have horizontally disposed members I5 integralwith and bent at right angle to the members I I and i2. The members I5retain the plastic composition in the enclosure I4. The members II andI2 are further provided with a plurality of apertures i6 which permitthe plastic composition to force itself from one enclosure to the otherthereby allowing an even distribution over the entire area and when theplastic material I0 is allowed to harden, due to a drying process, theplastic material in its various enclosures will be one integral massadherently joined and held in position.

If desired a floor covering of boards ll or any other composition may beplaced over the surface of the plastic material and be retained inposition by means of an adhesive binder or in any other convenientmanner.

It is obvious that the metal mesh consisting of sheet metal held in anupright position affords great strength and support for the plasticmaterial, and as this material is forced with equal pressure into allenclosures it will prevent the metal from bending or distorting whenpressure 50 is applied.

While I have herein disclosed with considerable particularity a singleembodiment of my invention, it will be manifest to persons skilled inthe art, that many changes in the general arrange- 55 ment, form, andconguration of the structure may be made and parts thereof may be variedwithin the scope of the appended claim.

Having thus described my invention what I claim and desire to secure byLetters Patent in the United States, is:

A building material of the character described comprising reinforcingmembers of fiat metal vertically disposed and arranged in angular inmtertting relation to one another so as to form rectangular enclosures,said vertical members having spaced right angle members alternatelydisposed at the loWer edge to provide integral support members forretaining a plastic composition between said vertical members, saidVertical members further having apertures adjacent the upper and loweredges to allow the plastic material to ilow evenly into all rectangularenclosures.
